GAS supplier Origin Energy wants to charge consumers about $40 a year more because of the carbon tax, in a new blow to family budgets.
It has applied to the price regulator to pass on the increase to consumers from July.
The Essential Services Commission of SA said yesterday Origin had applied for the increase to its standing contracts - the base contract used by the 25 per cent of SA households which have not signed a more competitive "market" contract. Any increase would be likely to set a precedent which would flow through to other contracts.
Origin is SA's biggest gas retailer, with a further 26 per cent of households on its market contracts.
In February, Santos predicted wholesale gas prices would more than double over the next couple of years.
That would result in a 10 per cent price rise for households.
This is in addition to pipeline operator Envestra adding $96 a year to the average SA gas bill of $693 from 2012-13.
ESCOSA said yesterday Origin wants to charge $1.70 per gigajoule of gas and $1.75/GJ from 2013-14.
SA households use an average 24 GJ of gas a year - meaning household gas bills would increase by $40 this coming year. ESCOSA has called for submissions from the public in response to Origin's request by April 13.
The Advertiser reported yesterday that SA will have the world's most expensive electricity as early as July.
An Energy Users Association of Australia report comparing 2011 prices in 92 countries, states or provinces, showed SA prices are the third highest behind Denmark and Germany.
